SPRING FITTING AND QUENCHING MACI-IINE. I

Specification of Letters Patent. Pggtgnfed Aug, 8, 1922,

Application filed January 16, 19.22. Serial No. 523,554.

To all whom itmcy concern Be it known that we, Amos C J COLE and WALTER H. Fos'rnn, citizens of the United States, and LAWFORD TL FRY, a sub ect of the King'of Great Britain and lreland and the Isle'of Man, residing, respectively, in

,Lewistown, Mifllin County, Pennsylvania,

Lewistown, Mifflin County, Pennsylvania, and Yeagertown, Mifliin County, Pennsylvania, have invented certain Improvements in a Spring Fitting and Quenching Machine,

of which the following is a specification.

Our invention relates to certain improvements in apparatus for fitting and quenching)spring plates.

no object of our inventionis to provide twofleXible dies between which the spring clamped between the two dies.

The invention also relates to certain de tails, which-will be fullydescribed hereinafter, reference being had to the accompanyng drawings, in which:

Fig. 1 is a sectional view illustrating an apparatus in which two sets of dies are used so that when one set is submerged in the fluid, the other is elevated.

Fig. 2 is a sectional view on the line 22, Fig. 1;

Fig. 3 is a sectional view on the line 3-3, Fi 1, drawn to an enlarged scale Fig. 4 is a sectional view on the line let,

the upper die;

Fig. 6 is a detached perspective view of the lower die and Fig. 7 is a diagrammatic view show ng the flat spring plate on the lower die prior to being shaped by the curved upper die.

Referring to the drawings, 1 is a frame mounted in a foundation 2. Located on a floor 3 is the tank at containing the quenching oil, or other fluid. This tank is jacketed in the usual manner. 5, 5 are the carrying frames. One end of a rope 6 is attached to one frame 5 and the other end is attached to. the other frame 5. The rope passes around sheaves 7 in the upper portion of the inain frame 1. 8 is a cylinder and 9 is a piston rod, the outer end of which is attached to the rope 6 at 10 so that, when fluid under pressure enters one end "of the cylinder 8, onecarrying frame is lowered and the other is raised, and when flu d is admitted to the other end of the cylinder the position of thetwo carrying frames is reversed. The carrying frames are guided by a central standard 11 and side standards 1250 that the carrying frames, which are narrow, will enterthe tank 4 when lowered.

v 13 is the lower disconnected by links 14 to the lower portion of eachcarrying frame 5, This die is made as shown in Fig. 6 and consists of a thin plate 15 on which are secured a series of'bars 16. The plate 15 is a spring plate and can accommodate itself to the'upper die, as shown at 17, being made in a manner similar to the die 13. The upper die has a spring plate 18 and a series of cross bars19 similar to the bars 16 of the" lower di e. Secured to the carrying frame 5 is afcentral abutment 20, which comes in contact with the central portion of the upper die. The outer ends of the upper dieare connected by links 21 to a cross head 22 adapted to guideways 23 in the franieo andan adjusting screw 26 is threaded through this cross head and has its lower bearing in the abutment 20 and its 'upper'bearing in a head 27 mounted in the frame 5. This screw has a hand wheel 28 by which it isturned so as to bend the upper die to any degree desired. Carried by the -frame is perforated plate 29, which is located at one side of the dies in order to guide the upper die when it is raised and lowered. i

The head 27 is connected to the abutment 20 by plates 30 forming a movable member,

attached to across head .31 by studs 32. This cross head is secured to the lower end of piston 'rod 33, which extends into a cylinder 3% secured to the upper end of the frame 5. The piston on this cross head fits the cylinder. Fluid, under pressure, can be admitted to either end of this cylinder so as to raise or lower the parts which carry the upper die.

The operation is as follows: The upper die is raised by fluid under pressure in the cylinder 34: and the die is adjusted to any 'which carries the upper die. This movable member slldes vertically in the frame and 1s
